1. What are the main differences between screen printing and other printing?
   a. High Adaptability.Lithography,Relief Printing and Gravure are conventionally used on flat surface,Screen Printing can be used on curved surface,spherical surface,convexity and concave,as well as flat surface.
   b. Produces a thicker ink layer.Offset Printing and Relief Printing produce a 5um ink layer,Gravure 12um,Felxography Printing 10um. Screen Printing produces a 30um ink layer,even up to 1000um in PCB printing,hard to shell off.Also suitable for process printing.
   c. Higher Light Stability than other priting,that's why it's extremely perfect for outdoor usage.
   d. Suitable for Large Format.Up to 3m*4m.

2. Merits of Screen Printing
   a. Suitable for various ink.Such as water ink,UV ink,etc.
   b. Soft surface.Suitable for priting on soft stock like paper and cloth,as well as rigid stock like glass and ceramics.
   c. Low printing pressure.It's also a perfect choice printing on fragile stock.

3. What's the main usage of polyester screen printing mesh?
   a. Paper Printing--advertisement,calendar,ect.
      Signs Printing
      Offset Priting
      Package Printing
      Building Matierial Printing--wall paper.
   b. Plastics Printing
      Soft Plastic Plate--ethylene tools,plastic bags, etc. 
      Plastic scale plate--composite scale plate, etc.
      Accessories
   c. Wooden Ware Printing
      Art work--painte ware,wooden art work,tools,etc.
      Semi-finished Products--sports goods,wood board,ceiling,road signs,billboard,advertisement,etc.
   d. Metal Ware Printing
   e. Glass,Ceramics Printing
      Glass--mirror,glass plate,cup,bottle,etc.
      Ceramics--art work,container,cup,etc.
   f. Sings
      scale plate,instruction board,etc.
   g. Circuit Board Printing
      PCB,filmed PCB,etc.
   h. Dyeing--flags,cloth,towel,shirts,shoes,bags,etc.
   i. Leather Products Printing

4. Why Polyester Screen Mesh is the most widely used printing mesh?
   Polyester Screen Mesh is anti-solvent,anti-chemicals,durable in water and under high temperature.High dimensional stability even under high pressure,with a low elongation.

5. What Should Be Taken Into Consideration Choosing a Screen Printing Mesh?
   a. Printing Stock.Fibre fabric,paper products,glass,ceramics,metal,plastics,wooden products,electronics,etc.
   b. Ink Property.Ink drying,colour brightness,ink absorption of printing stock.
   c. Material and Merits of Screen Mesh.
   d. Printing Requirement.Printing speed,printing pressure,etc.
   e. Ink Volume.
   f. Roughness of Printing Stock.Lower Mesh Count for rough printing stock,like leather,towel.
   g. Precision of Picture.Higher Mesh Count for fine lines.

6. Type of Screen Printing Mesh?
   S: Small thread diameter and mesh thickness,large mesh opening.Suitable for fine picture,such as art and photo.
   T: Larger thread diameter and smaller mesh opening than T type.Suitable for picture made of lines and colors,and letters&characters.
   HD:The largest thread diameter and mesh thickness,lowest mesh opening.Suitable for picture made of thick lines.

7. How Screen Mesh Color Affects Printing?
   Yellow and white Silk Screen are the most used ones.Colored printing mesh prevents diffuse reflection in plate burning,white mesh doesn't.Diffuse reflection causes ghosting in print.Color is important especially in precise printing.

8. Storage of Silk Screen Mesh
   Off direct light,avoid exposure to strong ultraviolet radiation,in dry condition,in case aging and strength loss.
